Clicking hamburger icon on Toolbar does not open Navigation Drawer
I have this nav drawer which was working perfectly fine. Refactoring my code I removed all onOptionsItemSelecteds in activities and made all activities inherit from a base activity which extends AppComplatActivity and implements all the necessary methods. After this clicking on hamburger icon does not work any more even though I have syncstate () and every thing. Any clues why this is not working? One of the activities: public class MainActivity extends BaseActivity implements SearchFilterFragment.OnFragmentInteractionListener { NavigationView navigationView; DrawerLayout drawerLayout; private
